If you want action to be taken in response to the events of a week ago.
My heart goes out to all who were affected by the senseless violence last Friday. Mixing violent mentally ill people with children forced to spend 5 days a week concentrated in schools without meaningful defense is, and always will be, a bad idea. Defending our children is a good idea. Making it easier to assess and detain people with classic signs of developing mental illness, especially when responsible adults are fully aware of the issues, would also be a rational response. In at least 3 of the 4 most recent incidents this was the case. Two of those shooters were dismissed from academic programs due to their mental status -- unleashed, angry and confused, on the general public.
Since 2010, there have been 9 similar incident reported from China, where children of young age have been attacked, wounded and killed. The weapon was always a knife, but the damage was the same. Will we all soon be eating only with spoons?
Too bad the numerous positive US incidents, when mayhem is prevented by a rational, legal weapon owner, are not given the same press coverage.
